TWO-REEL SEWING-MACHIN E Specification of Letters Patent.

Application filed May 1, 1908.

PatentedAng. 24, 1909.

Serial No. 430,391.

To aZZ whom it may concern:

Be it known that 1, Denis FLiiNi-iciin, a subject of the King of Great Britain and Ireland, and residentat Clayton-le-Moors, in the county of Lancaster, England, have invented certain new and useful Improvements in Two-Reel SewingMachines, of which the following is a specification.

This invention relates to improvements in two-reel sewing machines and especially to the type of machine described in my prior United States patents 1 0. 8203M and No. 820355 both of May 1906 respectively, and to other pending United States applications,

the object of the present invention being to i provide improved means for retaining and positioning the reel case in its holder.

My invention will be fully described with reference to the accompanying 3 sheets of drawings in which,

Figure 1 is afront elevation of the reel case. Fig. 2 is a plan of Fig. 1. Fig. 3 is a sectional side elevation of Fig. 1. Fig. 4 is a similar view to Fig. 3 but with a cop in the reel case. Fig. 5 is an elevation of a portion of the device shown in Figs. 3 and l. Fig. 6 is an elevation of the reel case in its operative position and part of the work support of the machine which is shown in section. Fig. 7, a somewhat similar view to Fig. 6, but showing the reel case in position for being withdrawn from the machine. Fig. 8 an inverted plan of a detail hereafter referred to. Figs. 9 and 10 are two views of details of the machine. Figs. 11, 12, 13 and 14: are detail views.

In the drawings Z denotes the reel case for the under thread; 01 the hinged cover of the same; at a spindle secured to the interior of the reel case; 0 a bobbin; (Z thread wound upon the bobbin; m a disk of metal; on a bow split spring secured to the disk m,- n a bridge piece carried by the cover a of the reel case; 0 an adjustable spring plate secured to the bridge piece n cut away over the hole at; 0 a wire guide; 0 an upstanding peg secured to the cover of; the wire guide 0 being secured preferably to the peg- 0 a plate secured to the under side of the work support of the machine; p a recess cut in the plate 29 in which the rounded end of the peg 0 rests; r the pointed nose of the reel case cover of; Z the reel case holder which is pivoted to a work support Z The thread is drawn off the stationary reel (Z between the disk m and the inside of the reel case through the hole a between the top of the bridge piece 11 and the spring plate 0 which is secured and can be adjusted by a screw 0 to vary the tension on the under thread, and thence under the wire guide 0.

Fig. 6 represents the reel case Z in its working position supported in the reel case holder Z and Fig. 7 shows the position of these parts when the reel (Z is to be changed; these parts are not described as they form no part of my present invention.

The peg 0 which is secured upon the reel case cover a is rounded at its upper end and lies in the recess p in the plate 79 see Figs. 6 and 8.

The reel case Z fits loosely in its holder Z and when the reel case holder is in its work ing position the peg 0 extends far enough for its top just to clear the underside of that portion of the plate 79 which is recessed or 5 removed so as to form a boundary between the recessed and the thicker portion of the plate; this boundary consists of two straight lines at right angles to one another, lettered 72*. The peg 0 has its movement confined between these boundaries p, p, and this leaves the reel case Z free to adjust itself in its holder Z and maintain a clear space between the reel case Z and the interior of the reel case holder Ztthrough which space j the needle thread can be drawn or led by the revolving looper.

The loop of needle thread, not shown, as it is carried by the looper passes over the pointed nose 1" of the reel case cover 92 thence down the front of the reel case holder Z and around and over the back of the same and over the top of the peg 0 between the latter and the recess in the plate 79 The peg 0 in addition to retaining the reel case Z in its holder Z also serves to keep the pointed nose 1- of the cover a in line with the path of the looper.

By means of the devices described the under thread is kept under absolute control and at the desired state of tension and so that there is no possibility of it overrunning.

What I claim and desire to secure by Let ters Patent of the United States is 1. In a two reel sewing machine, the combination with a work support, of a recessed plate secured to the underside of the work support, a reel case holder pivoted to the work support, a reel case loosely mounted in said holder, a cover for the reel case, a peg on said cover having a rounded end e11- gaging in the recess in the plate so as to retain and position the reel case in its holder.

In a two reel sewing-machine, the combination with the work support, of a recessed plate secured to the underside of said support, said recess having two boundaries arranged at right angles to each other, a reel case holder pivoted to the work support, a reel .case loosely mounted in said holder, a

,cover for the reel case having an opening l therein through which the thread passes, a peg on said cover having a rounded end adapted to engage with the recess in the plate and having limited movement therein so as to retain and position the reel case in its holder, and a thread guide on said holder. In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
